Syntax
>> VOLUME (phase_name/PHASE: iphase) (CHANGE/DELTA)

Parent Command
> OBSERVATION

Subcommand
>>> MATERIAL
>>> MODEL

Description
This command selects as an observation type the total volume of phase iphase. This observation type refers either to the entire model domain or to the subdomain defined by a list of rock types. The phase name phase_name or phase number iphase, which depend on the EOS module being used, are listed in the iTOUGH2 header. They can be specified either on the command line or using the subcommand >>>> PHASE. If keyword CHANGE is present, the change of the total volume since the first calibration time is computed. This option can be used, for example, to calculate the cumulative volumetric liquid flow which is equivalent to the change of the total gas volume in place.
